The image above represents diffusion coefficients. To calculate diffusion coefficients, four essential parameters are needed and these parameters are **Diffusion Coefficient (D _{1}), Time for Diffusion (t_{1}), Diffusion Coefficient (D_{2})Â **andÂ

**Time for Diffusion (t**

_{2}).**The formula for calculating the diffusion coefficient, D**_{1}:

_{1}:

D_{1}Â =Â ^{D2t2}/_{t1}

Where:

D_{1}Â = Diffusion Coefficient 1

D_{2} = diffusion coefficient 2

t_{1}Â = Time for Diffusion 1

t_{2} = time for diffusion 2

Given an example;

Find the diffusion coefficient 1 when the diffusion coefficient 2 is 4, the time for diffusion 1 is 8 and the time for diffusion is 10.

This implies that;

D_{2} = diffusion coefficient 2 = 4

t_{1} = Time for Diffusion 1 = 8

t_{2} = time for diffusion 2 = 10

D_{1}Â =Â ^{D2t2}/_{t1}

That is, D_{1}Â =Â ^{(8)(10)}/_{(4)}

D_{1}Â =Â ^{(80)}/_{(4)}

D_{1} = 20

Therefore, theÂ **diffusion coefficient 1Â **isÂ **20 g/mol.**

**Calculating the Diffusion Coefficient 2 when the Diffusion Coefficient 1, the Time for Diffusion 1 and the Time for Diffusion 2 are Given**

D_{2} = ^{D1 x t1} / _{t2}

Where:

D_{2} = diffusion coefficient 2

D_{1}Â = Diffusion Coefficient 1

t_{1}Â = Time for Diffusion 1

t_{2} = time for diffusion 2

Given an example;

Find the diffusion coefficient 2 when the diffusion coefficient 1 is 10, the time for diffusion 1 is 2 and the time for diffusion 2 is 5.

This implies that;

D_{1} = Diffusion Coefficient 1 = 10

t_{1} = Time for Diffusion 1 = 2

t_{2} = time for diffusion 2 = 5

D_{2} = ^{D1 x t1} / _{t2}

So, D_{2} = ^{10 x 2} / _{5}

D_{2} = ^{20} / _{5}

D_{2} = 4

Therefore, theÂ **diffusion coefficient 2Â **isÂ **4 g/mol.**

**Calculating the Time for Diffusion 1 when the Diffusion Coefficient 1, the Diffusion Coefficient 2 and the Time for Diffusion 2 are Given**

t_{1} = ^{D2 x t2} / _{D1}

Where:

t_{1}Â = Time for Diffusion 1

D_{1}Â = Diffusion Coefficient 1

D_{2} = diffusion coefficient 2

t_{2} = time for diffusion 2

Let’s solve an example;

Find the time for diffusion 1 when the diffusion coefficient 1 is 10, the diffusion coefficient 2 is 8 and the time for diffusion 2 is 4.

This implies that;

D_{1} = Diffusion Coefficient 1 = 10

D_{2} = diffusion coefficient 2 = 8

t_{2} = time for diffusion 2 = 4

t_{1} = ^{D2 x t2} / _{D1}

So, t_{1} = ^{8 x 4} / _{10}

t_{1} = ^{32} / _{10}

t_{1} = 3.2

Therefore, theÂ **time for diffusion 1Â **isÂ **3.2.**

**Calculating the Time for Diffusion 2 when the Diffusion Coefficient 1, the Diffusion Coefficient 2 and the Time for Diffusion 1 are Given**

t_{2} = ^{D1 x t1} / _{D2}

Where:

t_{2} = time for diffusion 2

D_{1}Â = Diffusion Coefficient 1

D_{2} = diffusion coefficient 2

t_{1} = Time for Diffusion 1

Let’s solve an example;

Find the time for diffusion 2 when the diffusion coefficient 1 is 8, the diffusion coefficient 2 is 12 and the time for diffusion is 6.

This implies that;

D_{1} = Diffusion Coefficient 1 = 8

D_{2} = diffusion coefficient 2 = 12

t_{1} = Time for Diffusion 1 = 6

t_{2} = ^{D1 x t1} / _{D2}

So, t_{2} = ^{8 x 6} / _{12}

t_{2} = ^{48} / _{12}

t_{2} = 4

Therefore, theÂ **time for diffusion 2Â **isÂ **4.**
